What are the best GCC flags to compile mysql 5.5.8?
My configuration:
CentOS 5.5 64-bit
GCC 4.5.2
CMake 2.8.3
glib-2.12.3
glibc-2.5-49
1. I need to compile mysql 5.5.8 through GCC from source to make it run as fast as possible just on one server. What are the best flags to compile mysql 5.5.8 on a concrete server?
I've been recomended the next flags from one enthusiast:
CFLAGS="-march=native -mtune=native -O3 -pipe -static-libgcc -fomit-frame-pointer -mfpmath=both ffast-math -fno-rtti -felide-constructors -fno-exception" CXXFLAGS="${CFLAGS}" cmake -DBUILD_CONFIG=mysql_release
Are they good and enough?
2. How can I know which flags adds -DBUILD_CONFIG=mysql_release after the build has been configured?
